IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base:

256986 Description of the Microsoft Windows Registry


When printing, SNA Server Print Server will insert its own carriage return/line feed (CR/LF) at the column that is indicated in the Default Page Width value in the Printer Properties. However, some print jobs control their CR/LF with 3270 Orders using Set Buffer Address (SBA), in an SCS Code ('15' EBCDIC or '0A' ASCII), and/or in Escape Sequences (either in transparent sections or not).

NOTE: The Escape sequence that tells the printer to do the wrapping is:

<Esc>&s0C <-End-of-line wrap = 0

0 = enable End of line Wrap
1 = Disable End of Line Wrap


A fix is available to correct this problem. To prevent SNA Print Server from inserting its own CR/LF, apply the fix referenced below and then edit the registry as follows:

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

  1. Start Registry Editor (Regedt32.exe or Regedit.exe, as appropriate for your version of Windows NT).
  2. Go to the following key in the registry:

    HKEY_LOCAL_ MACHINE\system\currentcontrolset\ 
  3. On the Edit menu, click Add Value and use the following entry:

    Value Name: LineWrap
    Data Type: REG_SZ

  4. Click OK.
  5. In the String field, input the string TRUE and then click OK.
  6. Stop SNAPrint Service and SNA Server Manager.
  7. Copy the fixed DLLs to the <Snaroot>\System directory.
  8. Restart SNAPrint Service and SNA Server Manager.


Microsoft has confirmed this to be a problem in SNA Server 3.0 and 3.0 Service Pack 1 (SP1). This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):



The definition of End Of Line Wrap, as stated in the PCL 5 Comparison Guide Manual, part no. 5961-0941, is:

When end of line wrap is enabled, a character or space that moves the cursor to the right of the right margin executes a CR-LF(prior to the printing of the character or space).
